What happens if the relative speed between the rotating flux of stator and rotor of the induction motor is zero?
if the relative speed of magnetic flux of stator and rotor becomes zero there will be no back emf and eventually the rotor gets zero speed
Technical team names for electronics engineers?
zero flux given
What are the functions of the flux ingredients?
to remove oxides to the surface being soldered
When pole flux of dc motor is zero what is its speed?
when the pole flux is zero there is no induced emf in the armature conductor of dc machine as a result of this there is no back emf for controlling action so speed become dangerously high or we can say it will be infinite.
What is the relation between voltage and magnetic flux?
A magnet field is the area surrounding a magnet within which the effects of that field may be observed.A magnetic field is represented by imaginary lines of force that we call magnetic flux. Magnetic flux (symbol, the Greek letter phi) is measured in webers (pronounced 'vay-bers'); the intensity of the magnetic flux is called magnetic flux density which is defined as the flux per unit area, measured in webers per square metre, which is given the special name, the tesla.
What is maximum and minimum electric flux?
As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.
What does magnetic flux mean in physics?
The magnetic flux is the measure of the strength of a magnetic field. The total magnetic flux through a closed surface is zero, according to Gauss's law for magnetism.
A Gaussian surface does not enclose a charge Does it mean that E equals 0 on its surface?
No.there can be electric field on the Gaussian surface even if the charge enclosed by it is zero.However ,net flux will be zero through the surface.
What are the two main types of flux?
Types of flux - Electric and Magnetic Flux. Electric field flux through a closed surface is equal to the change enclosed in the surface, or the rate of change of magnetic flux is equal to the induced voltage around the surface.
What is the direction of heat flux on isothermal surface?
Direction of heat flux on an isothermal surface is always normal to the surface.
When electric flux is zero then electric field is also zero why?
The electric flux depends on charge, when the charge is zero the flux is zero. The electric field depends also on the charge. Thus when the electric flux is zero , the electric field is also zero for the same reason, zero charge. Phi= integral E.dA= integral zcDdA = zcQ Phi is zcQ and depends on charge Q, as does E.
How does the tilt of the axis change your year?
When the planet's axis is tilted, it means that during orbit, for the hemisphere whose axis is tilted towards the sun, its surface will be more perpendicular with regard the direction of travel of light from the sun to the planet. Conversely, if the axis is tilted away from the sun, its surface will be less perpendicular. The solar energy obtained by a surface is directly proportional to the flux of photons and the flux is dependend on the angle between the surface and the direction of photon travel by the relationship f = f0sin(θ) where f is flux, f0 is the maximum flux, and θ is the angle between the surface and the direction of travel. We can see that if θ is 0 degrees (i.e. surface parallel to flow), the flux is zero, and if θ is 90 degrees (i.e. surface perpendicular to flow), the flux is the maximum flux. Therefore, the closer a surface is to perpendicularity with the direction of flow, the greater flux it gets. Therefore, the hemisphere whose part of the axis tilts toward the sun will be more perpendicular to the direction of flow and receive more solar energy while the other hemisphere receives less.
What happens if the relative speed between the rotating flux of stator and rotor of the induction motor is zero?
if the relative speed of magnetic flux of stator and rotor becomes zero there will be no back emf and eventually the rotor gets zero speed
What is flux inegral?
A flux integral is the summation of the component of a vector field perpendicular to differential surface areas (or in the direction of their normal vectors) over the entire surface. In other words, the flux of a vector field across a surface is the surface integral vector field in the direction of the normal component of the surface.INT INTS[(F*n)dS]INT INT is the double integral operatorS is the surface domain being integrated overF is a vector field* is the dot productn is the normal component to the surfacedS is the differential surface area.Flux integrals are very useful in physics. Two of Maxwell's equations involve flux integrals:INT INTS[(B*n)dS] = 0This equation states that the magnetic flux over a closed surface is always equal to zero. This equation reflects the fact that magnetic monopoles do not exist.INT INTS[(E*n)dS] = Q/EThis equation states that the electric flux through a closed surface is proportional to the total charge enclosed within that surface (1/E is the proportionality constant). These equations played important roles in the discovery of electromagnetic radiation.also the Flux of a velocity field through a surface indicates the flow rate across that surface.
Can there be any magnetic flux through closed surface?
no, a closed system is means if whats inside it remains as it is same as a closed surface, magnetic flux stays in place.
Why you use flux while welding?
Flux means to clean The flux becomes liquid, mixes with the molten puddle, picks up impurities and floats them to the surface.
What must be used in order to separate chemicals in a compound?
Richard Bader is a scientist from McMaster University who developed a way of dividing molecules into atoms. He uses zero flux surfaces to divide atoms. (A zero flux surface is a 2-D surface on which the charge density is a minimum perpendicular to the surface). Usually in molecular systems, the charge density reaches a minimum between atoms and this is a natural place to separate atoms from each other. more info- http://theory.cm.utexas.edu/bader/
